Single sentence, if possible. a) What is the main difference between a while loop and a do-while loop? b) What is the difference between Analog Wire and digitalWrite c) What is the duty cycle of a sure wave with a frequency of 10 Hand a positive puhe width the high time of 0.01 seconds? d) Considering the following schematic, what is your RI-6 Oms. R2-3 kobus and Vini 10 1) Can the position of the code and the cur circuit be swapped? Why why to e) Write a line of code to reset le, make ros) dhe lower forbis of varie A without affecting the remaining bits. Assume A is of type char Define stallone of a DC motor, Show the TTL-vel serial waveform for ASC code of being transmitted at 9600 band Label allanes (showing voltage levels and the duration of one bit) h) For the board shown, which of these LED circuits are wired correctlycie, LED is Page 1 of 6 Page 2 of 6 D Focus

can you please solve the whole question

Answer 1

a) while look :- While loop excute the statements in the look after verifying the condition Do while look ? So while look execute the statements in the look before verifying the condition. b) Digital write Digital write give only two voltage states 2) - High/ low (ie su dov) Analog write Analog write gave the different voltages varying between o and 5v based on their Duty cycle. c) Given Frequency (f) = 10Hz , on time = 0.03 Sec Timeperiod (7) = + = = =0.1 sec - on time %100 = 0.03 %100 Duty cycle = on time toff time 0.1

Duteyele = 0.03 *100 = 30 % Dutycrycle is 30% d) Güven Vin=lov R, = 6kn. R2 = 3kn Yout is the voltage across resistor R2 By Applying voltage division Rule Vin x Rz Vout. = 2 Ri+R2 10x. 3K 10 8k+ 3k ? =0.33V Voltage across Resistor (R2) = 0.330
